Praw

7.1.0

------------------
  
  **Added**
  
  * :class:`.Rule` to represent one rule of a subreddit.
  * :class:`.SubredditRules` to get and add rules.
  * Ability to submit polls with :meth:`.submit_poll`.
  * :class:`.PollData` and :class:`.PollOption`.
  * Ability to view poll data and poll options via the ``.poll_data`` attribute
  on poll submissions.
  * Add method :meth:`~.Reddit.delete` to :class:`.Reddit` class to support HTTP
  DELETE requests.
  * Added :class:`.CalendarConfiguration` to represent the configuration of a
  :class:`.Calendar` widget.
  * Added :class:`.Hover` to represent the hover state of a :class:`.Button`.
  * Added :class:`.Styles` to represent widget styling information.
  * Ability to stream live thread updates via new class
  :class:`.LiveThreadStream` with method :meth:`~.LiveThreadStream.updates`.
  
  **Changed**
  
  * :meth:`.RemovalReason.update`\ 's parameters are now optional.
  * :meth:`.SubredditRemovalReasons.__getitem__` now takes integers and slices to
  get removal reasons from the list of reasons as returned by Reddit.
  
  **Deprecated**
  
  * :attr:`.WebSocketException.original_exception` is deprecated and slated for removal in PRAW 8.0.
  
  **Fixed**
  
  * An issue where certain subreddit settings could not be set through
  :meth:`.SubredditModeration.update`, such as ``welcome_message_enabled``
  and ``welcome_message_text``. This change also removes the need for PRAW
  to track current subreddit settings and send unmodified ones in the
  update request.
  * Instances of ``BadRequest``\ s captured by PRAW that do not contain any
  detailed JSON data are re-raised as the original ``BadRequest``.
  * :meth:`.submit_image` and :meth:`.submit_video` will throw
  :class:`.MediaPostFailed` when Reddit fails to post an image or video post.

7.0.0

------------------
  
  **Added**
  
  * ``config_interpolation`` parameter for :class:`.Reddit` supporting basic and
  extended modes.
  * Add :meth:`.Redditors.partial_redditors` that returns lightweight redditor
  objects that contain only a few fields. This is useful for resolving
  Redditor IDs to their usernames in bulk.
  * :meth:`.User.friends` has a new parameter ``user`` that takes either an
  instance of :class:`.Redditor` or a string containing a redditor name and
  returns an instance of :class:`.Redditor` if the authenticated user is
  friends with the user, otherwise throws an exception.
  * :meth:`.SubmissionModeration.flair` has the parameter ``flair_template_id``
  for applying flairs with template IDs.
  * :meth:`~.Emoji.update` supports modifying an emoji's permissions.
  * :meth:`~.SubredditEmoji.add` now supports optionally passing booleans to set
  an emoji's permissions upon upload.
  * Methods :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` contain a new parameter,
  ``fetch``, that toggles the automatic fetching of existing data from Reddit.
  It is set to True by default.
  * Values in methods :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` that are left as the
  defaults will no longer be over-written if the ``fetch`` parameter is set to
  ``True``, but will fill in existing values for the flair template.
  * The parameter ``text`` for methods
  :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` is no longer required.
  * There is a new method, :meth:`.Subreddit.post_requirements`, to fetch a
  subreddit's post requirements.
  * Method :meth:`.SubmissionModeration.sticky` will now ignore the Confict
  exception generated by trying to sticky the same post multiple times.
  * A new method :meth:`.CommentModeration.show` will uncollapse a
  comment that was collapsed because of Crowd Control
  * Methods :meth:`.Subreddit.submit_image` and :meth:`.Subreddit.submit_video`
  will throw :class:`.TooLargeMediaException` if the submitted media is
  rejected by Reddit due to the size of the media.
  * Class :class:`.Reddit` has an attribute, ``validate_on_submit``, that can be
  set after class initialization that causes methods :meth:`.Subreddit.submit`,
  :meth:`.Subreddit.submit_image`, :meth:`.Subreddit.submit_video`, and
  :meth:`.Submission.edit` to check that the submission matches a subreddit's
  post validation rules. This attribute will be functionally useless once
  Reddit implements their change. This attribute will be deprecated on the next
  release after Reddit's change, and will be removed on the next major release
  after Reddit's change.
  
  .. warning:: In May-June 2020, Reddit will force all submissions to run through
  a subreddit's validation rules.
  
  * Introduced a data class, :class:`.RedditErrorItem`, to represent an
  individual error item returned from Reddit.
  * Class :class:`.RedditAPIException` now serves as a container for the
  :class:`.RedditErrorItem`\ s. You can access the items by doing
  ``RedditAPIException.items``, which returns a list.
  * :class:`.APIException` is an alias to :class:`.RedditAPIException`.
  * Parameter ``discussion_type`` to methods :meth:`.Subreddit.submit`,
  :meth:`.Subreddit.submit_image`, and :meth:`.Subreddit.submit_video` to
  support submitting as a live discussion (set to ``CHAT``).
  * Instances of :class:`.Trophy` can be compared for equality with each other.
  * :class:`.Reddit` has a new configurable parameter, ``timeout``. This defaults
  to 16 seconds. It controls how long PRAW will wait for a response before
  throwing an exception.
  * PRAW now handles ratelimit errors returned as instances of
  :class:`.RedditAPIException`.
  * :class:`.Reddit` has one new parameter, ``ratelimit_seconds`` . The parameter
  configures the maximum amount of seconds to catch ratelimits for.
  It defaults to 5 seconds when not specified.
  
  **Changed**
  
  * ``prawcore.BadRequest`` should no longer be raised. Instead a more useful
  :class:`.RedditAPIException` instance will be raised.
  * Set the default comment sort to ``confidence`` instead of ``best`` because it
  turns out ``best`` isn't actually the correct value for the parameter.
  
  **Deprecated**
  
  * :class:`.APIException` is deprecated and slated for removal in PRAW 8.0.
  
  **Fixed**
  
  * :meth:`.SubredditFlair.update` will not error out when the flair text
  contains quote marks.
  
  **Removed**
  
  * Converting :class:`.APIException` to string will no longer escape unicode
  characters.
  * Module ``praw.models.modaction`` no longer exists. Please use the module
  ``praw.models.mod_action``, or directly import ``ModAction``
  from ``praw.models``.
  * Methods :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` will no longer
  create flairs that are using an invalid template id, but instead throw a
  :class:`.InvalidFlairTemplateID`.
  * Method ``reddit.user.moderator_subreddits`` has been removed. Please use
  :meth:`.Redditor.moderated` instead.

  **Fixed**
  
  * Widgets of unknown types are parsed as ``Widget`` s rather than raising an
  exception

6.0.0

  **Removed**
  
  * ``Subreddit.submissions`` as the API endpoint backing the method is no
  more. See
  https://www.reddit.com/r/changelog/comments/7tus5f/update_to_search_api/.

5.4.0

------------------
  
  **Added**

  an infinite loop when ``"before"`` parameter is provided.
  
  **Removed**

5.3.0

------------------
  
  **Added**
  
  * :attr:`.Multireddit.stream`, to stream submissions and comments from a
  Multireddit.
  * :meth:`.Redditor.block`
  
  **Fixed**
  
  * Now raises ``prawcore.UnavailableForLegalReasons`` instead of an
  ``AssertionError`` when encountering a HTTP 451 response.

5.2.0

------------------
  
  **Changed**
  
  * An attribute on :class:`.LiveUpdate` now works as lazy attribute (i.e.
  populate an attribute when the attribute is first accessed).
  
  **Deprecated**
  
  * ``subreddit.comments.gilded`` because there isn't actually an endpoint that
  returns only gilded comments. Use ``subreddit.gilded`` instead.
  
  **Fixed**
  
  * Removed ``comment.permalink()`` because ``comment.permalink`` is now an
  attribute returned by Reddit.

5.1.0

------------------
  
  **Added**
  
  * :attr:`.Redditor.stream`, with methods :meth:`.RedditorStream.submissions()`
  and :meth:`.RedditorStream.comments()` to stream a Redditor's
  comments or submissions
  * :class:`.RedditorStream` has been added to facilitate
  :attr:`.Redditor.stream`
  * :meth:`.Inbox.collapse` to mark messages as collapsed.
  * :meth:`.Inbox.uncollapse` to mark messages as uncollapsed.
  * Raise :class:`.ClientException` when calling :meth:`~.Comment.refresh` when
  the comment does not appear in the resulting comment tree.
  * :meth:`.Submission.crosspost` to crosspost to a subreddit.
  
  **Fixed**
  
  * Calling :meth:`~.Comment.refresh` on a directly fetched, deeply nested
  :class:`.Comment` will additionally pull in as many parent comments as
  possible (currently 8) enabling significantly quicker traversal to the
  top-most :class:`.Comment` via successive :meth:`.parent()` calls.
  * Calling :meth:`~.Comment.refresh` previously could have resulted in a
  ``AttributeError: "MoreComments" object has no attribute "_replies"``
  exception. This situation will now result in a :class:`.ClientException`.
  * Properly handle ``BAD_CSS_NAME`` errors when uploading stylesheet images with
  invalid filenames. Previously an ``AssertionError`` was raised.
  * :class:`.Submission`'s ``gilded`` attribute properly returns the expected
  value from reddit.

5.0.1

------------------
  
  **Fixed**
  
  * Calls to :meth:`.hide()` and :meth:`.unhide()` properly batch into requests
  of 50 submissions at a time.
  * Lowered the average maximum delay between inactive stream checks by 4x to 16
  seconds. It was previously 64 seconds, which was too long.

5.0.0

------------------
  
  **Added**
  
  * :meth:`.Comment.disable_inbox_replies`, :meth:`.Comment.enable_inbox_replies`
  :meth:`.Submission.disable_inbox_replies`, and
  :meth:`.Submission.enable_inbox_replies` to toggle inbox replies on comments
  and submissions.
  
  **Changed**
  
  * ``cloudsearch`` is no longer the default syntax for
  :meth:`.Subreddit.search`. ``lucene`` is now the default
  syntax so that PRAW's default is aligned with Reddit's default.
  * :meth:`.Reddit.info` will now take either a list of fullnames
  or a single URL string.
  * :meth:`.Subreddit.submit` accepts a flair template ID and text.
  
  **Fixed**
  
  * Fix accessing :attr:`.LiveUpdate.contrib` raises ``AttributeError``.
  
  **Removed**
  
  * Iterating directly over :class:`.SubredditRelationship` (e.g.,
  ``subreddit.banned``, ``subreddit.contributor``, ``subreddit.moderator``,
  etc) and :class:`.SubredditFlair` is no longer possible. Iterate instead over
  their callables, e.g. ``subreddit.banned()`` and ``subreddit.flair()``.
  * The following methods are removed:
  ``Subreddit.mod.approve``, ``Subreddit.mod.distinguish``,
  ``Subreddit.mod.ignore_reports``, ``Subreddit.mod.remove``,
  ``Subreddit.mod.undistinguish``, ``Subreddit.mod.unignore_reports``.
  * Support for passing a :class:`.Submission` to :meth:`.SubredditFlair.set`
  is removed.
  * The ``thing`` argument to :meth:`.SubredditFlair.set` is removed.
  * Return values from :meth:`.Comment.block`, :meth:`.Message.block`,
  :meth:`.SubredditMessage.block`, :meth:`.SubredditFlair.delete`,
  :meth:`.friend`, :meth:`.Redditor.message`, :meth:`.Subreddit.message`,
  :meth:`.select`, and :meth:`.unfriend` are removed as they do not provide
  any useful information.
  * ``praw.ini`` no longer reads in ``http_proxy`` and ``https_proxy`` settings.
  * ``is_link`` parameter of :meth:`.SubredditRedditorFlairTemplates.add` and
  :meth:`.SubredditRedditorFlairTemplates.clear`. Use
  :class:`.SubredditLinkFlairTemplates` instead.

4.6.0

------------------
  
  The release's sole purpose is to announce the deprecation of the ``is_link``
  parameter as described below:
  
  **Added**
  
  * :attr:`.SubredditFlair.link_templates` to manage link flair templates.
  
  **Deprecated**
  
  * ``is_link`` parameter of :meth:`.SubredditRedditorFlairTemplates.add` and
  :meth:`.SubredditRedditorFlairTemplates.clear`. Use
  :class:`.SubredditLinkFlairTemplates` instead.

4.5.1

------------------
  
  **Fixed**
  
  * Calling :meth:`.parent` works on :class:`.Comment` instances obtained via
  :meth:`.comment_replies`.

4.5.0

------------------
  
  **Added**
  
  * :meth:`~praw.models.reddit.subreddit.Modmail.unread_count` to get unread
  count by conversation state.

  conversations.
  * :meth:`~praw.models.ModmailConversation.mute` to mute modmail conversations.
  * :meth:`~praw.models.ModmailConversation.unmute` to unmute modmail
  conversations.
  * :meth:`~praw.models.ModmailConversation.archive` to archive modmail
  conversations.
  * :meth:`~praw.models.ModmailConversation.unarchive` to unarchive modmail

  **Changed**
  
  * :meth:`.submit` accepts ``selftext=''`` to create a title-only submission.
  * :class:`.Reddit` accepts ``requestor_class=cls`` for a customized requestor
  class and ``requestor_kwargs={"param": value}`` for passing arguments to
  requestor initialization.
  * :meth:`~praw.models.reddit.subreddit.SubredditStream.comments`,
  :meth:`~praw.models.reddit.subreddit.SubredditStream.submissions`, and
  :meth:`~praw.models.Subreddits.stream` accept a ``pause_after`` argument to
  allow pausing of the stream. The default value of ``None`` retains the
  preexisting behavior.
  
  **Deprecated**
  
  * ``cloudsearch`` will no longer be the default syntax for
  :meth:`.Subreddit.search` in PRAW 5. Instead ``lucene`` will be the default
  syntax so that PRAW's default is aligned with Reddit's default.
  
  **Fixed**
  
  * Fix bug where :class:`.WikiPage` revisions with deleted authors caused
  ``TypeError``.

  * Uploading an invalid image raises func:`APIException`.

  ``reddit.subreddit("subreddit").moderator()``) will contain attributes with
  the relationship metadata (e.g., ``mod_permissions``).
  * :class:`.Message` instances retrieved from the inbox now have attributes
  ``author``, ``dest`` ``replies`` and ``subreddit`` properly converted to
  their appropriate PRAW model.

  * :meth:`.LiveContributorRelationship.leave` to abdicate the live thread

  status.

  not provide any useful information.
  
  **Fixed**
  
  * :meth:`.hide()` and :meth:`.unhide()` now accept a list of additional
  submissions.
  * :meth:`.replace_more` is now recoverable. Previously, when an exception was
  raised during the work done by :meth:`.replace_more`, all unreplaced
  :class:`.MoreComments` instances were lost. Now :class:`.MoreComments`
  instances are only removed once their children have been added to the
  :class:`.CommentForest` enabling callers of :meth:`.replace_more` to call the
  method as many times as required to complete the replacement.
  * Working with contributors on :class:`.SubredditWiki` is done consistently

  * :class:`.SubredditFilters` to work with filters for special subreddits, like

  passed.

  accidentally missed previously.

  **Changed**
  
  * :meth:`.me` now caches its result in order to reduce redundant requests for
  methods that depend on it. Set ``use_cache=False`` when calling to bypass the
  cache.
  * :meth:`.replace_more` can be called on :class:`.Comment` ``replies``.
  
  **Deprecated**

  4.2 as it was never intended to be part of it to begin with.
  * Iterating directly over :class:`.SubredditRelationship` (e.g.,
  ``subreddit.banned``, ``subreddit.contributor``, ``subreddit.moderator``,
  etc) and :class:`.SubredditFlair` will be removed in PRAW 5. Iterate instead
  over their callables, e.g. ``subreddit.banned()`` and ``subreddit.flair()``.
  * The following methods are deprecated to be removed in PRAW 5 and are replaced
  with similar ``Comment.mod...`` and ``Submission.mod...`` alternatives:
  ``Subreddit.mod.approve``, ``Subreddit.mod.distinguish``,
  ``Subreddit.mod.ignore_reports``, ``Subreddit.mod.remove``,
  ``Subreddit.mod.undistinguish``, ``Subreddit.mod.unignore_reports``.
  * Support for passing a :class:`.Submission` to :meth:`.SubredditFlair.set`
  will be removed in PRAW 5. Use :meth:`.flair` instead.
  * The ``thing`` argument to :meth:`.SubredditFlair.set` is replaced with
  ``redditor`` and will be removed in PRAW 5.
  
  **Fixed**
  
  * :meth:`.SubredditModeration.update` accurately updates
  ``exclude_banned_modqueue``, ``header_hover_text``, ``show_media`` and
  ``show_media_preview`` values.
  * Instances of :class:`.Comment` obtained through the inbox (including
  mentions) are now refreshable.
  * Searching ``/r/all`` should now work as intended for all users.
  * Accessing an invalid attribute on an instance of :class:`.Message` will raise
  :py:class:`.AttributeError` instead of :class:`.PRAWException`.

------------------
  
  **Fixed**
  
  * Fix bug where ipython tries to access attribute
  ``_ipython_canary_method_should_not_exist_`` resulting in a useless fetch.
  * Fix bug where Comment replies becomes ``[]`` after attempting to access an
  invalid attribute on the Comment.
  * Reddit.wiki[...] converts the passed in page name to lower case as pages are
  only saved in lower case and non-lower case page names results in a Redirect
  exception (thanks pcjonathan).

4.0.0rc3

---------------------
  
  **Added**
  
  * ``implicit`` parameter to :meth:`.url` to support the implicit flow for
  **installed** applications (see:

  * :meth:`.scopes` to discover which scopes are available to the current
  authentication
  * Lots of documentation: https://praw.readthedocs.io/
